Module Data, Status, and Channel
Configuration
After installing the 1762-IR4 RTD/resistance input module, you must
configure it for operation, usually using the programming software
compatible with the controller (for example, RSLogix 500™). Once
configuration is complete and reflected in ladder logic, you will need
to get the module up and running and then verify its operation. This
chapter includes information on the following:
•
module memory map
•
accessing input image file data
•
configuring channels
•
configuring periodic calibration
•
preparing ladder logic to reflect the configuration
•
running the module
•
verifying the configuration
Module Memory Map The module uses six input words for data and status bits (input
image), and five configuration words.
